GRAIN-BINDER.

Specification of Letters Patent.

' Patented June 27,1916.

Application filed April 30, 1914. 3 Serial No. 835,393.

To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and ation in the length of the grain. I attain this object by providing improved means operatively connected to a grain adjuster whereby, as the length of the grain varies, the binding mechanism is automatically adjusted so as to vary the position of the band in accordance with the length of'the grain, all as hereinafter more fully set forth.

In the accompanying drawings I have, for purposes of illustration, shown one embodiment which my invention may assume in practice.

In these drawings: Figure 1 is a plan view of a binder equipped with my 'improvement. Fig. 2 is a sectional view on line 22 of Fig. 1. Fig. 3 is an end View taken approximately on line 3-3 of Fig. 1 looking in the direction of the arrow.

The binder shown is of standard construction comprising a frame having a fixed upper deck 1 and a longitudinally shiftable lower deck 2 on which is mounted the frame 3 of the binding mechanism. As in the.

usual construction, this binding mechanism is driven from suitable gearing 4 and comprises the usual elements, including a needle 5, discharge arms 6, spring sheaf guides 7, and a knotter breast plate 8. Further, as in the usual construction, the knotter breast plate is also preferably connected to a diagonally and longitudinally extending supplemental frame member 9 and is provided with a. stubblewardly extending extension 10 movable longitudinally beneath a longitudinally extending guide or. bail 1'1 fixed to the upper deck'L- The binder is further also provided with a head adjuster 12 p votally connected at 13 to the upper deck and with a butt adjuster .14 of any desired type,

shown to' be of the endless butter type, .pivotally connected on a shaft 15 in such a manner that it may be continuously driven from the elevator mechanism of the harvester in the usual way.

In my improvement the binding mechanism is adjusted automatically upon variation in the length of the grain.

mechanism andthe grain adjusting mechanism, as, for instance, in the embodiment herein illustrated, the head adjuster 12. As shown,

this adjuster is provided with a spring 16 operatively connected between the same and a fixed part of the upper deck 1 and normally tending to pull the adjuster inward to a point slightly :inside of the full line position shown in Fig. 1'. It is'further provided with agrainwardly extending diagonally disposedshank 17 movable therewith about the pivot 13 and itself pivotally connected to a transversely and diagonally disposed rod 18 extending across the upper deck, which rod is in turn resiliently and slidably connected .through opposing springs 19, 20 on the opposite sides of its point of connection, to an eye 21 on aJ-transversely extending frame 22. In the opposite ends of this frame are journaled shafts 23, 24 carrying sprockets 25,26 which are connected by a chain 27. As shown, the shaft 23 is also provided with a second sprocket 28 connected through 'a chain 29 with a sprocket 30 on the butter shaft 15 so that continuous rotation 'is imparted through this connection to the sprocket 26. Beneaththi's sprocket a suitable beveled gear 31(Figs. 2 and 3) is fixed sotha't' it rotates with the sprocket, and this beveled gear is normally positioned in a neutral position between. a plurality of co6perating, preferably rigidly connected, beveled gears 32, 33 carried on a threaded member or worm 34. This worm 34 is preferably supported at one'end in a bracket 35 upon the upper deck 1 between the gears 32, 33 and at its forward end is pivotally connected at 36 to a supplemental arm. 37 projecting grainwardly from the binder frame 3,

which arm, if desired, maybe formed in.-

tegral with that frame. This arm 37 is also preferably connected through a longitudinally extending member 38 with a pin 39 This is brought about in the embodiment shown herein by a connection between the binding 'ther carried on the top of the frame 22 at a point between the point of connection of the spring pressed rod 18 and that of the sprocket26, a longitudinally extending slot ber 38.

' The operation of my improved construc tion is as follows: Let us assume that the parts are in the full line position shown in Figs. 1 .and 3, wherein the beveled gear 31 is in its neutral position between the beveled gears 32, 33. If the grain coming over the binder deck increases in length, it will obviously force out the head adjuster 12 toward the dotted line position shown, against the tension of the spring 16. This will cause the shank 17 on the head adjuster to be thrown toward the dotted line position shown and will project the rod 18 in a forward direction longitudinally of the upper deck. Necessarily, through the connection of this rod to the frame 22, the latter frame will then be thrown toward the right, which will result in the continuously rotating beveled gear 31 being-thrown into engagement with the then stationary gear 33 in such a manner that the latter will feed the threaded member 34: toward the left and thereby draw the binding mechanism toward the left, so that the needle 5 is moved fartoward the heads of the grain and the band upon the grain when the needle is operated, will of necessity be nearer the heads. This movement of the binding mechanism and the threaded member 3 will continueuntil the pin 39 on the frame 22 abuts against the end of the slot 40, whereupon the beveled gear 31 will be thrown out of meshwith the gear 33 and into its neutral position, thus interrupting the adjustment of the binding mechanism. In other words, as the grain increases in length, means are provided for adjusting the band upon the sheaves so that the position of this band is automatically varied with the length of the grain and the band is always maintained in the desired relative position between the heads and butts. Conversely, should shorter grain come over the binder deck, the beveled gear 31 would obviously be connected with the beveled gear 32 in such a manner as to feed the binding mechanism in the opposite direction. Here it will, of course, also be understood that the length of the slot 40 may be adjusted for operation of the mechanism between any predetermined limits, and that in lieu of the particular form of limiting and adjusting.

connection shown, any other suitable mechan1sm.may be used to accomplish its purposes.

shown herein'is used for purposes of illus- I tration and that the spirit of my invention may be embodied in other forms of construction than that illustrated.
